So I'm pretty sure that I'm going to get the Greddy E-Manage Ultimate. What I'm wondering is if I should go ahead and get some adjustable Cam Gears as well and get it all tuned at the same time. Also what are some specific benefits of getting tuned with the adjustable cams gears?

The only cam you can adjust on the 5Gen Preludes is the intake cam. If you adjust the exhaust cams, the sensors in the distributor get out of sync with the sensors on the crankshaft and will cause a check engine light.

Generally tuning via cam gears will allow you to shift the power band of the engine. They won't necessarily make more power (but they can).

from what i have heard and been told, the ultimate is not very good with vtec engines..u would be better off going with the e-manage blue ecu

I plan on replacing the water pump (I really want to get an electric but they're so expensive) and timing belt so I figured that would be the best time to install the cam gears. Which ones do you think I should go with?

I have a set of STR Pro Series gears (now BDL). Excellent quality. I also like the new Skunk2 Pro Series cam gears. I'm planning to use them on my next build. Fidanza cam gears also look nicely made, as do Bisimoto cam gears.

So I have done some research into this and I definitely want to get my car tuned for lower end power <4k rpm's. I live in downtown Denver and never go over 40mph unless I get on the highway to go to the mountains and I have to go 80mph to hit 4k rpm.

Two questions about this. 1. Can you tune the timing and overlap for better mpg as well as power?

2. Wouldn't you get better gas mileage if you tune for the lower rpm's since you should be at a lower rpm for the same speed?
